[PATCH] sh: I/O routine cleanups and ioremap() overhaul

This introduces a few changes in the way that the I/O routines are defined on
SH, specifically so that things like the iomap API properly wrap through the
machvec for board-specific quirks.

In addition to this, the old p3_ioremap() work is converted to a more generic
__ioremap() that will map through the PMB if it's available, or fall back on
page tables for everything else.

An alpha-like IO_CONCAT is also added so we can start to clean up the
board-specific io.h mess, which will be handled in board update patches..

[PATCH] sh: IRQ handler updates

This moves the various IRQ controller drivers into a new subdirectory, and
also extends the INTC2 IRQ handler to also deal with SH7760 and SH7780
interrupts, rather than just ST-40.

The old CONFIG_SH_GENERIC has also been removed from the IRQ definitions, as
new ports are expected to be based off of CONFIG_SH_UNKNOWN.  Since there are
plenty of incompatible machvecs, CONFIG_SH_GENERIC doesn't make sense anymore.

[PATCH] fix arm26 THREAD_SIZE

arm26 currently has a 256 kB THREAD_SIZE (sic).

Looking at the comment in the code, this seems to be based on a
misunderstanding.

The comment says:
this needs attention (see kernel/fork.c which gets a nice div by zero if
this is lower than 8*32768

kernel/fork.c does:
  max_threads = mempages / (8 * THREAD_SIZE / PAGE_SIZE)

Therefore, a division by 0 is impossible for all reasonable cases with
THREAD_SIZE >= PAGE_SIZE.

Since the minimum PAGE_SIZE Linux uses on the arm26 architecture is 16k,
PAGE_SIZE should be sufficient for THREAD_SIZE.

[PATCH] Mark some key VFS functions as __always_inline

Mark a few VFS functions as mandatory inline (based on Al Viro's request);
these must be inline due to stack usage issues during a recursive loop that
happens during the recursive symlink resolution (symlink to a symlink to a
symlink ..)

This patch at this point does not change behavior and is for documentation

Mark a number of functions as 'must inline'.  The functions affected by this
patch need to be inlined because they use knowledge that their arguments are

[PATCH] enable unit-at-a-time optimisations for gcc4

Allow gcc4 compilers to optimize unit-at-a-time.

This flag enables gcc to "see" the entire C file before making optimisation
decisions such as inline, which results in gcc making better decisions.  One
of the immediate effects of this is that static functions that are used only
once now get inlined.

gcc 3.4 has this flag as well, however gcc 3.x have a problem with inlining
and stacks and as a result, enabling this flag there would cause excessive and
unacceptable stack use.  This problem is fixed in the gcc 4.x series.  The
x86-64 architecture already enables this feature so it's well tested already.

[PATCH] Make __always_inline actually force always inlining

This patch is the first in a series that tries to optimize the kernel in terms
of size (and thus cache behavior, both cpu and pagecache).

This first patch changes __always_inline to be a forced inline instead of the
"regular" inline it was on everything except alpha.  This forced inline
matches the intention of the define better as a matter of documentation.
There is no change in behavior by this patch, since "inline" currently is
mapped to a forced inline anyway.

[PATCH] gx1fb: (try to) play nicer with various BIOSes

Seems that the CS5530A chip used in Geode GX1 systems has some crazy feature
that causes SMI traps when accessing the PCI configuration space of the video
device.  Various GX1 BIOSes seem to use this 'feature' to hide the real BARs
of the device.  This patch disables these traps (in an early PCI fixup) so
that Linux sees the real, physical BARs and not the virtual ones provided by
the BIOS.

This should allow the GX1 framebuffer driver to work on more systems that have
different BIOSes as the driver no longer guesses at what the virtual BARs
mean.

I'm not entirely sure it the correct solution as I can neither test regular
VGA console nor the X's 'cyrix' video driver so there might be some breakage
there -- probably best to get some more testers before applying it.

[PATCH] neofb: take existing display configuration as default

On a Dell Latitude CPi-A I noticed a strangeness wrt.  the handling of an
external monitor by the neomagic framebuffer driver, namely when the laptop is
docked in a C/Dock II with the lid shut.

A cold boot would result in the BIOS configuring the video chip to use the
"external monitor only" mode, yet neofb would default to "internal LCD only".
An attempt for a quick fix by using the Fn-F8 keystroke to toggle the display
combination modes resulted in a reproductible hard lock, powering down being
the only solution.

The attached patch makes neofb probe the register for the current display
mode, using that value as a default if nothing was specified as kernel/module
parameter.

[PATCH] dell_rbu: fix Bug 5854

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=5854

Root cause:

The dell_rbu driver creates entries in /sys/class/firmware/dell_rbu/ by
calling request_firmware_nowait (without hotplug ) this function inturn
starts a kernel thread which creates the entries in
/sys/class/firmware/dell_rbu/loading , data and the thread waits on the
user action to return control back to the callback fucntion of dell_rbu.
The thread calls wait_on_completion which puts it in a D state until the
user action happens.  If there is no user action happening the load average
goes up as the thread D state is taken in to account.  Also after
downloading the BIOS image the enrties go away momentarily but they are
recreated from the callback function in dell_rbu.  This causes the thread
to get recreated causing the load average to permenently stay around 1.

Fix:

The dell_rbu also creates the entry
/sys/devices/platform/dell_rbu/image_type at driver load time.  The image
type by default is mono if required the user can echo packet to image_type
to make the BIOS update mechanism using packets.  Also by echoing init in
to image_type the /sys/class/firmware/dell_rbu entries can be created.

The driver code was changed to not create /sys/class/firmware/dell_rbu
entries during load time, and also to not create the above entries from the
callback function.  The entries are only created by echoing init to
/sys/devices/platform/dell_rbu/image_type The user now needs to create the
entries to download the image monolithic or packet.  This fixes the issue
since the kernel thread only is created when ever the user is ready to
download the BIOS image; this minimizes the life span of the kernel thread
and the load average goes back to normal.

[PATCH] cpuset oom lock fix

The problem, reported in:

  http://bugzilla.kernel.org/show_bug.cgi?id=5859

and by various other email messages and lkml posts is that the cpuset hook
in the oom (out of memory) code can try to take a cpuset semaphore while
holding the tasklist_lock (a spinlock).

One must not sleep while holding a spinlock.

The fix seems easy enough - move the cpuset semaphore region outside the
tasklist_lock region.

This required a few lines of mechanism to implement.  The oom code where
the locking needs to be changed does not have access to the cpuset locks,
which are internal to kernel/cpuset.c only.  So I provided a couple more
cpuset interface routines, available to the rest of the kernel, which
simple take and drop the lock needed here (cpusets callback_sem).
